UNITED STATES CHARLES A. BOIBER, OF NEW BRITAIN, GONNECTICUT,A8SIGNOB OFONE-EAL! TO THOMAS KOBYLAZ, OF NEW BRITAIN, CONNECTICUT.

' Application filed December 13, 1928. Serial No. 680,336.

To all whom it may concern:

Be it known that 1, CHARLES A. Boers, a citizen of Poland, residing atNew Britain, in the county of Hartford and 5 State of Connecticut, haveinvented certain new and useful improvements in Clamp- Lock Combinationsfor Auto Hoods, of which the following is a specification.

My invention relates to improvements in l clamp-lock combinations forauto-hoods adapted for use with auto-hoods for locking the same in theclosed position, operating generally after the manner of the auto-hoodlock that is shown and described in my ending application, Serial No.513,319, filed anuary 18, 1923, and the object of my improvement is toproduce a structure in which the key-operated lock mechanism and theclamp structure are more closely associated and are substantiallystructurally united and inter-built so as to reduce the number of thestructural elements, to simplify the construction, to provide arelatively compact structure, and improve the efiiciency andreliability. y

In the accompanying drawing Figure 1 is a side elevation of part of thestructure of an automobile showing the hood and the adjacent part of thechassis and so with a hood-clamp made in accordance with my invention,being; in the closed or locked position, and adapted to be released bythe use of a key;

Figure 2 is a plan view on' an enlarged scaleof the hood clamp-lockcombination only, the key-hole being covered by the cover-cap.

Figure 3 is a sectional view on the line 3-3 of Fig. 2, with parts inside elevation and parts broken away.

,Figure 4 is a similar view with the parts in a difi'erent position. Myimproved clamp-lock combination for auto-hoods comprises a compositebody 5 structure that is vertically elongated and has a keyhole 11 inthe top end face, that has its lower end 12 pivotally connected to thechassis 13, and that is provided adjacent the upper end with a laterallydirected hook 14. In the locked position the hook 14 is engaged with anopening 15 in an eye piece or lug 16 that is supported from the sidewall of the hood 17.

In the unlocked posi 'on the book 14; is

. raised from the locked position so as to clear the eye piece or lug16, as is common, and involving relative movement of the two parts ofthe composite body structure 10, said two parts comprising what may bedesignated as the upper or outer part 17 and the lower or inner part 18.The hook 14: is on the upper part 17 and the pivotal connection of thelower end mentioned is provided by means of the lower part 18 The upperpart 17 is also provided with a laterally directed handle-lug 19 and mayalso have a cover-cap 20 for: covering the keyhole 11. As a detail, thepivotal connection 21 for said cover-cap20 may be provided in the formof a yielding springplunger device substantially as shown and describedin the application mentioned.

In the present instance the upper part 17-.

is provided with a bore 22 that extends continuously through the samelongitudinally from end to end and that has the lower end portion 23enlarged to provide a spring chamber for the spring 24. An annularscrew-cap 25 may serve as a closure for the bottom end of the springchamber 23.

The lower part 18 has an eye 26 at the lower end that has an opening 27for the pivotal connection and above said eye 26 is substantially in theform of acontinuous, straight rod oi uniform and circular form ofcross-section and which is a fit for the upper portion 28 of the bore22.

Said rod or body portion 29 of the lower part 18 projects upwardlythrough the endcap or screw-ca 25, through the spring chamber 23, andinto the upper-portion 28 o the bore 22, said up er portion 28 and theadjacent upper en portion 80 of the rod 29 being adapted to cooperate ascylinder and plunger.

The spring 2i tends to pull the upperpprt 17 downwardly and the upperpart is h ed in opposition to said spring 24. The lower end of thespring 24 abuts against the ca 25 and the upper end cooperates with 9.d1- ametral pin 31 that projects through the rod 29. In the closed andlocked position the upper face of the pin 31 may be seated against theopposed top wall or roof 82 of the spring chamber, the efiect thereofbemg to limit the closing movement of the upper part 17 and the lowerpart 18 that is eflected through the medium oi. the spnng24. That is tosay,-the pin 31 serves as a limiting stop for limiting the relativemovement of the parts.

The upper end portion 30 of the rod 29 serves in the present instance asthe barrel member of the key-operated locking mechanism, the keyhole 11mentioned being'providedtherein in the form of a narrow longitudinallydirected slot 33 that is a fit for the flat blade portion 34 of the key34:. Said 4 locking mechanism is represented conventionally and maybebriefly designated as follows structure of the parts brought intoregistration the devices are in unlocked position or condition so thatfree relative movement of the upper art 17 and the lower part will bepermitted? The locking and unlocking are effected substantially 1n thesame manner as with a Yale lock of standard form.

I claim as my invention A clamp-lock combination for auto-hoodscomprising an upper part and a lower art telescopically connectedtogether and Ea ing a spring that tends to draw said parts together tothe closed osition, said upper part having a bore and a portion of saidlower part fitting and operatlvely housed within said bore, key operatedlocking mechanism comprising spring tumblers, and said spring tumblersbeing operativel housed in opposed and adjacent portions 0 the wall ofsaid bore and said portion of the lower part.

CHARLES A. BOBER.
